Somewhat? Browser cookies can literally contain anything (not just session identifiers, or authentication tokens), I've only heard JWT pronounced "Jay-double you-tea" (but maybe that's regional), Macaroons[0] and Maracrons[1] are French (given clever-cloud is french, this is strange), OPA doesn't need to be server side.
You skipped an important part of the quote from RFC-7519[0] (later replaced by two RFCs[1],[2] without the strange suggestion):
> The suggested pronunciation of JWT is the same as the English word "jot".
Replaced by RFC-7797[1] and RFC-8725[2], neither of which have the pronunciation suggestion. There was also an errata about the pronunciation line[3], which probably explains the mismatch.
I don't, so perhaps I'm just doomed not to understand, but I still don't get that? I would never pronounce it 'jaught' either (nor know what someone meant if they did).
